CROSSHEAD Filed Feb. 16. 1927 2 Sheets-Sheet 2 ATTOR N EY Patented July 14, 1931 WALTER n. HENRY, or BAnTIMon'u, MARYLAND onossnnnn Application filed February 16, 1927. Serial No'."168,715.

This invention relates to improvements in locomotive cross heads and their guides, the general object of the invention being. to provide-means for taking care of all wear, both L? lateral and'vertical that appears between the shoes and theguide bars.

Another object of the invention to so" form the parts that adjustment can be made to take up wear by moving the shoes towards.

l0 theguide bar and also by moving the bars towards the shoes, thus giving a double adjustment which-will take care of about 1 of wear before repairs are necessary so that the life of the shoes and guide bars is greatly increased.

Another object of the invention is to so form theiparts that the wedges are clamped in adjusted position by the securing bolts and the wedges .will remain in position even though some of the bolts should work loose.

Another object of the invention is to provide rack means for moving the wedges, portions of which are carried by some of the bolts.

This invention also consists in certain other features ofconstruction and in the combina-' tion and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and-specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is an elevation of the improved cross head. 1

Figure 2 is a section on line 22 of Figurex3.-

Figure 3 is an end view with the guides shown in section.

Figure 1s a section on line 4- of Figure 1.

Figure 5 is a section on line 5-5 of Fig urel.

Figure 6 is a perspective view of one of the wedges.

Figure 7 is a fragmentary'view of a modification. f 3 I 1 Figure 8 isan edge view of Figure 7.

In these drawings, 1 indicates the body of the cross head and 2 indicates theshoes for engagingthe guides 3. The shoes areconnected wit-hthe bodyby means of the bolts 6,

these bolts-passing through elongated holes 7 formedin the shoes so that the shoes have; limited vertical movement relative ,to the: body; *l/Vedges 8 are placed between the shoes and body toadjust the shoes in relation to the body and these wedges are of angle shape-in cross section, as clearly shown in F igure 6,.

, Each wedge isprovided with the rackiteeth' 9on a portion of its enlarged end. andathe'front'bolt of each rowofbolts'is V formedwith the two sets of teeth 10 for en gaging'the rackteeth so that. when this bolt is-turned by' awrench or the like engaging the square end: 10 of the bolt,.the-two wedges engaged by the bolt will be moved in. one direction or the other according to. the direction;of.rotation of the bolt.

Thus ;when:the shoesneed adjusting,lit is simply necessaryto loosen the nuts of the bolts and then to turn the front-bolts to move the wedges inwardly to force the shoes outwardly and'then the nutsv of the bolts are tightened to'holdthe shoes in adjusted position. As will be seenfrom Figures 4 and: 5, by making the wedgesof angle shape incross section, portions of the wedges will be clamped betweenrthe body and shoesso that the wedges will be firmly held in adjusted position;

Of course, the engagem'entof the teeth of the front bolts with the rack teeth of the front: wedges 1n wedges will also act to hold the adjusted position.

small end bolt and of eachiwedge, which will strike a thus limit the movement of the.

wedge in one direction while a pin or projection 13, carried by the shoe, limits the movement of the wedge inthe opposite direction by the small end of the wedge strikingthe I said pin.

F gures 7 i and 8 show a modified form ofthe- I invention in which the two upper and the two lower wedges are connected together by the bight 14 so that each pair of wedges forms a U-shaped member.

As shown in the drawings, the wedges are put in place from the front end of the cross head which is more accessible than the rear and this will permit greater space at the rear of the cross head for the main rod.

From the foregoing, it will be seen that I have provided means whereby the shoes can be easily and quickly adjusted on the cross head and the shoes are firmly fastened in ad justed position through'the clamping action of the bolts and also through the toothed connection between the front bolts and the wedges.

I also make the guide bars3 with V or wedge-shaped inner faces, as shown at 3 which engage V-shaped recesses 2 formed in the outer faces of the shoes. By this arrangement the adjustment of the shoes towards the guide barswill take up all wear, lateral as well as vertical, and it also permits wear to betaken up by adjustment of the bars towardeach other. This will enable the bars to be adjusted toward each other after the shoes have been adjusted to their full extent so that a double adjustment is secured whichwill take care of about 1% of wear before repairs are necessary so that the life of the shoes and guide bars is greatly increased. lVhen the limit of adjustment of the shoes has beenreached the wedges are returned to their original positions and then the guide bars are moved against the shoes, it being understood that the bars as now arranged are capable of this adjustment. Then lhe shoes can be adjusted by their wedges a second time. 7

As will be seen the wedges are then held in place by the bolts even though some of the bolts should work loose.

To adjust't-he cross head the bolts are all loosened to release the wedges and then the wedges are adjusted, after which the bolts are tightened. The plain bolts must be tightened first so that they will lock the wedges inposition and to prevent them from moving when the adjusting bolts are tightened.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

lVhat I claim is 1. I11 a cross head of the class described, wedges for adjusting the shoes on the head, each wedge having a rack part, bolts for connecting the shoe with the head, at least One of the bolts having teeth engaging the rack teeth for adjusting the wedges when the bolts are turned.
